Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of an image projection device for projecting an image on a microfilm.

[0002]

Image projection devices are widely used for projecting images recorded on microfilm. This image projection device includes a microfilm reader for enlarging and viewing a microfilm image on a screen,
There are a microfilm reader / printer having a function of copying an image in addition to a function of projecting an image, a microfilm scanner for reading an image of a microfilm by a CCD which is a solid-state image sensor, and the like.

There is a type of microfilm in which image information is imprinted on each frame of a long roll-shaped film. In an image projection device for searching or copying the roll-shaped microfilm, the microfilm is sent out. A roll film carrier which is a device is provided detachably or integrally incorporated. A roll film carrier provided in a reader / printer or the like is capable of performing a vertical scan for correcting a vertical displacement of an image projected on a screen. The vertical scan is performed by moving the roll film carrier from an original position (hereinafter, referred to as a home position) along a direction orthogonal to the transport direction of the microfilm. Conventionally, as a method of moving the roll film carrier, a method of moving the roll film carrier by a driving force of a motor and a method of manually moving a roll film carrier exposed to the image projection device by an operator are used. There is a method of moving the carrier.

By the way, since microfilms are generally stored and used in large quantities, when using microfilms, a desired image can be quickly retrieved from a large amount of microfilms. Copying etc. is required. When searching or copying a microfilm, in the past, the microfilm was stored,
The held cartridges were sequentially loaded manually into the roll film carrier, and the used cartridges were manually discharged from the roll film carrier. As described above, the operator manually ejects a cartridge and loads a new cartridge, that is, replaces a cartridge, each time a search, a copy, or the like is completed for each cartridge. For this reason, it has been pointed out that it takes time and effort to replace the cartridge, and it is difficult to quickly search or copy the microfilm.

In order to deal with such a problem, recently,
Cartridge loaders have been developed for automatically loading and unloading cartridges containing microfilm.
This cartridge loader is attached to an image projection device such as a reader / printer as an auxiliary device,
It has a cartridge storage part capable of storing a plurality of cartridges. An opening for inserting and removing a cartridge to be stored is formed in the cartridge storage portion, and a plurality of cartridges are inserted through this opening and stored in the cartridge storage portion. Further, the cartridge storage section is detachably attached to a main body such as a reader / printer. Such a cartridge storage portion is referred to as a cartridge container or a stacker, and will be referred to as a stacker in the following description. Then, the cartridge loader automatically sequentially takes out the cartridges stored in the stacker and loads them into the roll film carrier, and when the micro film search or copying is completed in the roll film carrier, the used cartridges are removed. It is designed to be taken out from the roll film carrier and returned to the stacker.

[0006]

When a cartridge loader loads or returns a cartridge, the relative position between the roll film carrier and the cartridge loader is a position at which the cartridge can be loaded or returned (hereinafter, referred to as "position"). Called neutral position). However, if the vertical scan function is used during the search for the microfilm, the roll film carrier moves from the home position, and the relative position between the roll film carrier and the cartridge loader shifts. Is not in neutral position.
As it is, it will not be possible to return the cartridge loaded in the roll film carrier to the stacker, so when replacing the cartridge, correct the deviation in the relative position between the roll film carrier and the cartridge loader, Both need to be returned to the neutral position.

Here, it is possible to correct the deviation of the relative position by returning the roll film carrier to the home position. That is, when the movement of the roll film carrier in the vertical scan is performed by the stepping motor, the drive pulse number of the stepping motor in the vertical scan is counted and the movement amount of the roll film carrier is stored.
When the search is completed, if the stepping motor is driven in the reverse rotation with the same number of drive pulses as the counted, the roll film carrier returns to the home position and the displacement of the relative position with the cartridge loader is corrected. Will be.

However, when the operator manually moves the roll film carrier to perform a vertical scan, the movement amount of the roll film carrier cannot be stored, and the roll film carrier must be returned to the home position. I can't. Therefore, in order to move the roll film carrier side and correct the displacement of the relative position to the cartridge loader, it is limited to the case where the vertical scan is performed electrically, and the manual vertical scan must be prohibited. There was a problem.

In the image projection apparatus equipped with the cartridge loader, the following problems have been pointed out. Some cartridge loaders detect the number of cartridges stored in the stacker at the time when the loading or discharging operation of the cartridges is started, and determine the number of cartridge replacements based on the detected number of cartridges. is there. In such a cartridge loader, if the number of cartridges is increased or decreased during the operation, it not only causes a malfunction of the cartridge loader but also hinders the retrieval and copying of the microfilm. In addition, when the maximum number of cartridges in the stacker is stored in this stacker for searching, etc., the cartridge is further loaded when the cartridge is loaded in the roll film carrier.
If an additional piece is stored in the stacker, the cartridge loaded in the roll film carrier cannot be returned, and the cartridge loader will not function properly. Also, depending on the timing of increasing or decreasing the number of cartridges in the stacker, a cartridge transport error may occur,
The cartridge loader may not function properly.

Further, in the cartridge loader, in general, if the stacker is removed during the operation, there is a possibility that the cartridge may be conveyed incorrectly and the cartridge loader may not function properly.

Therefore, a first object of the present invention is to correct the displacement of the relative position between the roll film carrier and the cartridge loader and replace the cartridge even if the vertical scanning is manually performed. An object is to provide a projection device.

A second object of the present invention is to provide an image projection apparatus capable of preventing malfunction of the cartridge loader due to increase / decrease of the number of cartridges during the operation of the cartridge loader and thus improving reliability of microfilm retrieval and copying. To do.

A third object of the present invention is to provide an image projection apparatus capable of preventing malfunction of the cartridge loader due to removal of the stacker during operation of the cartridge loader, thereby improving reliability of microfilm retrieval and copying. To do.

The roll film carrier 1 via the mounting plate 115 or the like.
Therefore, the relative positions of the loading mechanism 22 and the stacker 24 with respect to the roll film carrier 1 do not shift even when a vertical scan is performed. However, since the ejection mechanism 23 in the cartridge loader 21 does not move in conjunction with the roll film carrier 1, the relative position with respect to the roll film carrier 1 is displaced when the vertical scan is performed. Therefore, in the present embodiment, as described below, the roll film carrier 1 is left at the position after the vertical scan, and the roll film carrier 1 is moved by the base plate 60 side of the discharge mechanism 23, so that the roll film carrier 1 is moved. 1 and the discharging mechanism 23 of the cartridge loader 21 are moved to the neutral position.

FIGS. 11 (1) to 11 (3) are conceptual diagrams showing a procedure for correcting the relative positional deviation between the roll film carrier 1 and the ejection mechanism 23 of the cartridge loader 21 caused by the vertical scan. In FIG. 1A, the base plate 60 is in the initial position, and the third and fourth sensors 8 are
The light-shielding plate 89 fixed to the roll film carrier 1 shields the light sources 3, 84 from light. At this time,
The roll film carrier 1 and the discharge mechanism 23 are in the neutral position.

FIG. 11B shows a state in which the vertical scan is performed and the roll film carrier 1 is moved to the front side (corresponding to the F direction in FIG. 3 and the P direction in FIG. 4) indicated by the solid arrow. Shows. The direction in which the vertical scan is performed is detected based on the states of the third and fourth sensors 83 and 84. That is, the third sensor 83 is turned on while being shielded by the light shielding plate 89, and the fourth sensor 84 is not shielded and is turned off. When the third sensor 83 is on and the fourth sensor 84 is off, it is detected that the vertical scanning direction is on the front side, and at this time, the fourth motor 75 is driven, for example, in the forward rotation to cause the base plate 60 to move in a direction indicated by a broken arrow. Move toward the front side indicated by. Then, when the fourth sensor 84 is turned on and the fourth motor 75 is stopped, the roll film carrier 1 and the discharge mechanism 23 move to the neutral position.

In FIG. 11C, the vertical scan is performed, and the roll film carrier 1 is on the depth side indicated by the solid line arrow (corresponding to the G direction in FIG. 3 and the N direction in FIG. 4).
It has been moved to. In this state, the third sensor 83 is turned off without being shielded from light, and the fourth sensor 84 is shielded from light by the light shielding plate 89 and remains on. When the third sensor 83 is off and the fourth sensor 84 is on, it is detected that the vertical scanning direction is on the depth side. At this time, the fourth motor 75 is driven to rotate in the reverse direction so that the base plate 60 is indicated by the broken line arrow. Move toward the depth side shown. Then, when the third sensor 83 is turned on and the fourth motor 75 is stopped, the roll film carrier 1 and the discharge mechanism 23 move to the neutral position.

The neutral position between the roll film carrier 1 and the cartridge loader 21 is different in absolute position with respect to the reader / printer main body when the roll film carrier 1 is at the home position and when it is corrected after the vertical scan. It will be. However, if the roll film carrier 1 and the cartridge loader 21 are in a relative neutral position, the cartridge loader 21 can perform a predetermined loading / unloading operation, so there is no problem even if the absolute positions with respect to the reader / printer main body are different. . Further, in order to detect the vertical scanning direction, it is necessary that one of the third sensor 83 and the fourth sensor 84 is shielded by the light shielding plate 89 and remains on. Therefore, the distance between the third sensor 83 and the fourth sensor 84, the width dimension of the light shielding plate 89, and the like are set in correspondence with the maximum distance that the roll film carrier 1 can move by the vertical scan.

In the cartridge loader 21 configured as described above, the original orientation of the cartridge A stored in the stacker 24 before being taken out by the loading mechanism 22 and the cartridge after being returned to the stacker 24 by the discharging mechanism 23. The direction of A is different. FIG. 14 is a perspective view showing a state where the reel 4 is taken out from the cartridge A, and shows an ANSI standard type cartridge. The present embodiment is not limited to this type of cartridge, but can be applied to, for example, a 3M type cartridge by appropriately modifying the shapes of the upper and lower arms 91, 92.

FIG. 16 is a schematic block diagram showing a control system of the entire reader / printer including the roll film carrier 1, the cartridge loader 21 and the like. Operation panel 84
The search device provided with is connected to the reader / printer, the roll film carrier 1, and the cartridge loader 21 via the interface, and further, is connected to the microcomputer M.
It is connected to C. The search information of the image information to be searched or copied is input by the operator operating the operation panel 84. Then, the microcomputer MC outputs a control signal for loading and unloading the cartridge A to the cartridge loader 21 based on the input search information, for example, from among the microfilms F accommodated in the cartridge A. A control signal for retrieving image information is output to the roll film carrier 1, and a control signal for retrieving the retrieved image information is output to a reader / printer. Microcomputer MC
Outputs a control signal for turning on the solenoid 51 while the cartridge loader 21 is operating, and moves the prohibiting lever 54 to a position covering the opening 24 a of the stacker 24. As a result, increase or decrease of the cartridge A in the stacker 24 during the operation of the cartridge loader 21 is prohibited. Further, the microcomputer MC outputs a control signal for keeping the moving claw portion 31 in the stacker 24 during the operation of the cartridge loader 21. As a result, the removal of the stacker 24 itself during the operation of the cartridge loader 21 is prohibited.

Further, in the present embodiment, the microcomputer MC controls the cartridge loader 21 as follows. Microcomputer MC
Is adapted to accept the switching of the operation mode of the cartridge loader 21 even when the cartridge loader 21 is in operation. For example, when performing automatic search or copy of the microfilm F in the auto mode and there is no image information matching the search information previously input by the operator, switch to the semi-auto mode and switch to the manual mode. The search can be performed, and the automatic mode can be searched again by returning to the auto mode. Moreover, the microcomputer MC
Is the cartridge A currently loaded in the roll film carrier 1 when the interrupt key 87 is operated and the interrupt mode is instructed when the cartridge loader 21 is operating in the automatic mode or the semi-auto mode.
After discharging, the operation mode is switched to the interrupt mode.

The microcomputer MC of the present embodiment further measures the amount of movement of the moving claw portion 31 from the initial position until the first cartridge A is set on the setting rod 33, and the amount of movement is set to this moving amount. Based on this, the number of cartridges A stored in the stacker 24 is recognized. The moving claw portion 31 moves from the initial position where the third switch 50 is on until the entire cartridge A group moves and the first cartridge A is set on the set rod 33, that is, the first switch 37 is turned on. Move until turned on. By measuring the moving amount of the moving claw portion 31 by the CPU or the counter of the microcomputer MC, the number of the cartridges A stored in the cartridge container 24 can be easily recognized. For example, when N cartridges A having the maximum capacity are stored in the stacker 24, the initial movement amount of the set rod 33 is, for example, Rmm, and the width of one cartridge A is, for example, 25.4 mm. Then, the number of cartridges is recognized as follows. For example, if the initial movement amount of the set rod 33 is Rmm plus 25.4 mm, the number of cartridges A stored in the stacker 24 is recognized as "N minus 1". In addition, the initial movement amount of the set rod 33 is Rmm plus (25.4 mm ×
In the case of 2), the number of the cartridges A stored in the cartridge container 24 is recognized as “N−2”. And microfilm MC
Determines that the number of exchanges required to exchange all the cartridges A is the number of the cartridges A minus 1, based on the number of the recognized cartridges A.

Next, the operation of this embodiment will be described. The reader / printer of this embodiment including the cartridge loader 21 has the three operation modes, that is, the auto mode, the semi-auto mode, and the interrupt mode, as described above. It is designed to be used. When the cartridge loader 21 is operating in these operation modes, the cartridge loader 21

In the next step S13, it is determined whether or not the third switch 50 is on, that is, whether or not the moving claw portion 31 of the loading mechanism 22 is located at the end in the D direction which is the initial position (see FIG. 3). . If the determination in step S13 is NO, the first motor 36 is driven in reverse rotation (S14), the third switch 50 is turned on, and it is determined that the moving claw portion 31 has moved to the initial position (S13). The 1-motor 36 stops (S15). In step S16, it is determined whether the first sensor 81 is on, that is, whether the slider 61 is located at the initial position (see FIG. 4). If the determination in step S16 is NO, the third motor 70 is driven to rotate normally (S17), the first sensor 81 is turned on, and the slider 61 is turned on.
Is determined to have moved to the initial position (S16), the third
The motor 70 stops (S18). When the slider 61 is in the initial position, the holder portion 62 faces the L direction. In step S19, it is determined whether the third sensor 83 and the fourth sensor 84 are on, that is, whether the base plate 60 is located at the initial position (neutral position with respect to the roll film carrier 1). If the determination in step S19 is NO, the roll film carrier 1 and the base plate 6 are determined based on the ON / OFF states of the third and fourth sensors 83, 84.
The displacement direction of the relative position to 0 is detected as described above (see the description of FIG. 11). When it is determined that the fourth motor 75 is appropriately rotationally driven in the normal and reverse directions according to the displacement direction (S20), the third and fourth sensors 83 and 84 are turned on, and the base plate 60 is moved to the initial position (S19). ), The fourth motor 7
5 stops (S21). Further, in step S22, the keep solenoid 106 is turned off, and the upper and lower arms 91, 92 of the holder portion 62 are rotated in the opening direction by the elastic force of the tension coil springs 97, 98. As described above, in the initial setting routine, the carrier front surface portion 38, the moving claw portion 31, the slider 61, the base plate 60, the upper and lower arms 91 and 92.
However, as shown in FIG. 17A, the initial position and the initial direction are set, respectively.

Increment / Inhibition Prohibition Processing for Cartridge A As shown in FIG. 34, in the cartridge increase / decrease inhibition routine, the inhibition lever 54 is moved. Step S
When a start switch (not shown) is turned on at 23, the solenoid 51 is turned on at step S24. As a result, as shown in FIG. 17B, the prohibiting lever 54 rotates about the support shaft 53 against the elastic force of the tension coil spring 55, and the opening 24 a of the stacker 24.
To the position where it covers. By moving the prohibiting lever 54 to this position, it is possible to prevent the cartridge A stored in the stacker 24 from being removed or a new cartridge A from being added during the operation of the cartridge loader 21. Until the search for the last cartridge A stored in the stacker 24 is completed and the cartridge A is returned to the stacker 24 (FIG. 25 (4)).
Although the prohibiting lever 54 is still protruding to the position where it covers the opening 24a, the prohibiting lever 54 is omitted in the operational state diagrams of FIGS. 17 to 28 except for a part thereof.

Loading of Cartridge A As shown in FIG. 35, in the cartridge loading routine, loading of the first cartridge A1 by the loading mechanism 22 is performed. In step S25, the moving claw portion 31
Is moved in the E direction from the initial position shown in FIG. 17 (1) when the first motor 36 is driven to rotate normally. The movement amount Smm of the moving claw portion 31 is measured by the CPU or the counter of the microcomputer MC and is temporarily stored in the RAM (S26). Moving claw part 31
A group of the cartridges A in the stacker 24 also moves in the E direction as the first cartridge A1 is set on the set rod 33.
Is turned on (S27). The number of cartridges A stored in the stacker 24 is recognized based on the moving amount of the moving claw portion 31 at this time, and the number of exchanges required to exchange all the stored cartridges A is determined.

When the first switch 37 is turned on, the first motor 36 reverses and is driven in reverse rotation, and the moving claw portion 31 reverses and moves in the D direction (S28). FIG. 17
As shown in (2), the moving claw portion 31 does not return to the initial position, that is, the position at which the third switch 50 is turned on, and the moving claw portion 31 moves to the third position.
When returning to a predetermined position in the stacker 24 before the switch 50, the first motor 36 is stopped and its movement is stopped (S28 to S30). Hereinafter, the predetermined position in the stacker 24 where the moving claw portion 31 stops will be referred to as a stacker stop position. The distance from the initial position of the moving claw portion 31 to the stop position inside the stacker is predetermined. By controlling the number of drive pulses input to the first motor 36, which is a stepping motor, the moving claw portion 31 is stopped at the in-stacker stop position even if the number of cartridges A stored in the stacker 24 is different. When the moving claw portion 31 stands by inside the stacker 24, the engaging portion 31a of the moving claw portion 31,
31b becomes freely engageable with the bottom wall of the stacker 24, which prevents the stacker 24 itself from being removed during the operation of the cartridge loader 21. The moving claw portion 31
The stop position within the stacker where the cartridge A stops within the stacker 24 is a position that does not interfere with the returning operation of the cartridge A to the stacker 24.

Next, in step S31, the front surface portion 38 of the carrier is moved from the closed position, which is the initial position shown in FIGS. Is rotated forward to the open position along the I direction ((3) in FIG. 18).
reference). By rotating the carrier front face portion 38 to the open position, the lock of the set rod 33 in which the cartridge A1 is set is released, and the set rod 33 moves from the stacker 24 side toward the carrier front face portion 38 side. As a result, as shown in FIG. 18C, the cartridge A1 is held by the carrier front surface portion 38 (S32). After that, the second motor 41 is driven to rotate forward, and the carrier front surface portion 38
Rotates in the H direction while holding the cartridge A1 (S33). With this rotation, the second switch 42
Is turned on, the second motor 41 is stopped (S34,
S35). As a result, the cartridge A1 is
As shown in (4), the roll film carrier 1 is positioned and loaded in the supply section 6. At the same time, the set rod 33 moves to the cartridge container 24 side and is locked again. Then, in the next step S36, the microfilm F contained in the first cartridge A1 loaded in the supply unit 6 is loaded from the rewinding reel 4 toward the winding reel 5.

When the loading of the microfilm F is completed, as shown in FIG. 19 (5), the slider portion 61 at the initial position reaches a predetermined position in front of the second sensor 82 by a certain distance in the K direction. Move only (S3
7). The predetermined position before the second sensor 82 at which the slider 61 stops is hereinafter referred to as the second sensor front stop position. At the second sensor front stop position, the holder portion 62 is held in a state of facing the M direction by the elastic force of the torsion coil spring 101. The distance from the initial position of the slider 61 to the stop position in front of the second sensor is predetermined, and by controlling the number of drive pulses input to the third motor 70, which is a stepping motor, the slider portion 61 moves in front of the second sensor. It is stopped at the stop position. At the second sensor front stop position where the slider 61 stops before the second sensor 82, when the vertical scan is performed, the upper and lower arms 91, 92, etc., which face the M direction, are located at the supply section of the roll film carrier 1. It is a position where it does not interfere with the cartridge A loaded in the cartridge 6. Thus, in the cartridge loading routine,
The moving claw portion 31 reciprocates from the initial position, the first cartridge A1 is loaded in the supply portion 6, and the microfilm F accommodated in this cartridge A1 is loaded. Further, the movable claw portion 31 stands by inside the stacker 24, which prevents the stacker 24 itself from being removed.

Searching Operation As shown in FIG. 36, in this searching routine, the cartridge A to be searched next is set on the set rod 33. In the roll film carrier 1, for the cartridge A loaded in the supply unit 6, while the microfilm F is being conveyed between the rewinding reel 4 and the winding reel 5, desired image information is manually searched or It is automatically searched.

While the roll film carrier 1 is being searched, in the cartridge loader 21, in step S40, the first motor 36 is driven to rotate normally, so that the moving claw portion 31 of the loading mechanism 22 becomes E. Moved in the direction. At this time, the moving amount of the moving claw portion 31 is equal to the width 2 of one cartridge A in addition to the first moving amount Smm counted and stored in step S26 described above.
It is a length obtained by adding 5.4 mm and minus the distance from the initial position of the moving claw portion 31 to the stop position inside the stacker. The cartridge A to be loaded next by the movement of the moving claw portion 31 as shown in FIG.
2 is set on the set rod 33.

When the moving claw portion 31 moves in the E direction by the predetermined distance, the first motor 36 immediately reverses and is driven by reverse rotation, and the moving claw portion 31 reverses and moves in the D direction. Yes (S41). As shown in FIG. 20 (1),
As in steps S28 to S30, the moving claw portion 31 does not return to the initial position but returns to the stop position inside the stacker,
The first motor 36 is stopped to stop its movement (S4
1 to S43). By waiting the moving claw portion 31 inside the stacker 24, the stacker 24 itself is prevented from being removed.

By the operation of the moving claw portion 31 returning to the stop position in the stacker, the cartridge A2 set on the set bar 33 remains sandwiched between the moving claw portion 31 and the first switch 37 and the like. Is prevented. As a result, the cartridge A2 is smoothly inserted into the carrier front surface portion 38. Further, even when the first cartridge A1 is set, the return movement operation of the moving claw portion 31 prevents the cartridge A1 from being sandwiched. The moving speed of the moving claw portion 31 is set to be higher than the moving speed when the first cartridge A1 is set when the second cartridge A2 and subsequent cartridges A are set. As described above, in the searching routine, the moving claw portion 31 of the loading mechanism 22 is reciprocated from the stop position in the stacker while searching the microfilm F, and the next cartridge A is loaded.
Are set on the set rod 33. Further, the stacker 24 itself is prevented from being removed.

By the way, in the reader / printer,
The vertical scan function may be used during retrieval or copying. In this case, as shown in FIG. 20 (2), the relative position between the roll film carrier 1 and the ejection mechanism 23 of the cartridge loader 21 is deviated. The state shown in the figure is
It shows a state in which the roll film carrier 1 is moved to the front side.

Replacement of Cartridge A As shown in FIGS. 37 to 39, in the cartridge replacement routine, ejection of the cartridge A1 loaded in the supply section 6 of the roll film carrier 1 and loading of the next new cartridge A2 are performed. , But almost simultaneously in parallel. The cartridge exchange routine is sequentially repeated until the final cartridge An is loaded. In the following description of this routine, the cartridge A1 ejection operation and the cartridge A2 loading operation will be described.

When the search for the microfilm F in the cartridge A1 loaded in the supply unit 6 is completed and a rewind signal is output (S45), the motor connected to the rewinding reel 4 is rotationally driven. Yes (S4
6) The rewinding of the microfilm F is started. When the drive shaft is reset (S47), driving of the motor is stopped (S48). As a result, the microfilm F is completely rewound on the rewinding reel 4, and the process proceeds to step S54.

When the rewind signal is output, the processes of steps S49 to S53 are performed in parallel with the rewind of the microfilm F (S46 to S48). First, it is determined whether the vertical scan has been executed based on the on / off states of the third and fourth sensors 83, 84 (S49). That is, the third and fourth sensors 8
It is determined that the vertical scan is not executed if one of the three and 84 is in the off state, and the vertical scan is not executed when both of them are in the on state. When the vertical scan is performed, the vertical scan direction is detected based on the states of the third and fourth sensors 83 and 84 (S50). Figure 11
As shown in (2), when the third sensor 83 is on and the fourth sensor 84 is off, it is detected that the vertical scanning direction is the front side, and as shown in FIG. When the sensor 83 is off and the fourth sensor 84 is on, the vertical scan direction is detected to be the depth side. Next, in step S51, the fourth motor 75 is appropriately rotationally driven in the forward and reverse directions based on the detected vertical scan direction. When the vertical scanning direction is on the front side, the fourth motor 75 is driven to rotate in the forward direction, and the base plate 60 moves toward the front side. When the vertical scan direction is on the depth side, the fourth motor 75 is reversely driven and the base plate 60 moves toward the depth side. In step S52, it is determined whether the base plate 60 and the roll film carrier 1 have moved to the neutral position, based on the states of the third and fourth sensors 83, 84. When the vertical scanning direction is on the front side, the base plate 6 is turned on when the fourth sensor 84 is turned on.
0 and the roll film carrier 1 are determined to have moved to the neutral position, and the fourth motor 75 is stopped (S
53). When the vertical scan direction is on the depth side, the base plate 6 is turned on when the third sensor 83 is turned on.
0 and the roll film carrier 1 are determined to have moved to the neutral position, and the fourth motor 75 is stopped (S
53).

The state shown in FIG. 20 (2) shows the case where the vertical scan direction is the front side. In this case, as shown in FIG. 21 (1), in steps S49 to S53 described above, the fourth motor 75 is driven to rotate in the forward direction to move the base plate 60 toward the front side indicated by the arrow, 6
0 and the roll film carrier 1 are moved to the neutral position.

In step S54, the third motor 70
Is reversely driven, and the slider 61 moves in the K direction from the second sensor front stop position. As shown in FIG. 21B, the second sensor 82 is turned on and the slider 61 is moved to the K position.
When it is detected that it has reached the stop position at the end of the direction,
The third motor 70 is stopped, and the slider 61 stops its movement (S55, S56). At this time, the base plate 60 and the roll film carrier 1 have moved to the neutral position, and when the slider 61 moves to the stop position at the end in the K direction, the position of the holder portion 62 facing the M direction is
It corresponds to the position of the supply section 6 of the roll film carrier 1. In this state, the keep solenoid 106 is turned on (S57), and the pressing plate 99 swings in a direction of pressing the pressing portions 95 and 96 of the upper and lower arms 91 and 92. As a result, the upper and lower arms 91, 92 have tension coil springs 97,
The cartridge A1 loaded in the supply unit 6 is held by being rotated in the closing direction against the elastic force of 98 (state of FIG. 21 (2)).

The flow is now step S58.
The flow is divided into the flow of steps S63 to S66 and the flow of steps S64 to S66. First, the processing of steps S64 to S66 will be described. The slider 61 holding the cartridge A1 in step S57 moves in the J direction by the forward rotation of the third motor 70 (S64). As shown in FIG. 22 (3), when the first sensor 81 is turned on and it is detected that the slider 61 has moved to the initial position, the third motor 70 is stopped and the slider 61 stops its movement ( S65, S66). In addition, the slider 61
When is moved to the initial position, due to the action of the roller 112 and the guide plate 113, the holder portion 62 faces the L direction while holding the cartridge A1.

Next, the processing of steps S58 to S63 will be described. The front surface 38 of the carrier from which the cartridge A1 has been taken out is rotated 90 degrees in the I direction from the closed position to the open position (S58), the lock of the set rod 33 is released, and the next new cartridge A2 is transferred to the front surface 38 of the carrier. 22 (3) (see FIG. 22 (3)). The front surface 38 of the carrier, which holds the cartridge A2 and is located at the open position, rotates in the H direction while holding the cartridge A2 in steps S60 to S62. This allows
The cartridge A2 is positioned and loaded in the supply section 6 of the roll film carrier 1 as shown in FIG. At the same time, the set rod 33 moves to the cartridge container 24 side and is locked again. Then, the newly loaded microfilm F in the cartridge A2 is loaded (S63).

In step S67, the base plate 60 moves in the P direction by the forward rotation of the fourth motor 75 (S67). As shown in FIG. 22 (4), when the fifth sensor 85 is turned on and it is detected that the base plate 60 has moved to the stop position at the end in the P direction, the fourth motor 75 is stopped and the base plate 60 is stopped. Stops its movement (S
68, S69). By this movement of the base plate 60, the cartridge A1 held by the holder portion 62 is returned to the rearmost position in the stacker 24 through the second window portion 134 and the return port. The cartridge A1 is returned to the stacker 24 in the direction opposite to the storage direction of the unused cartridge A that has not been searched yet. In this state, the keep solenoid 106 is turned off (S70), and the pressing plate 99 swings in a direction to release the pressing of the pressing portions 95 and 96 of the upper and lower arms 91 and 92. Thereby, the upper and lower arms 91, 92 are
The cartridge A returned to the stacker 24 by being rotated in the opening direction by the elastic force of the tension coil springs 97 and 98.
Release the hold of 1.

When the holding of the cartridge A1 is released,
The base plate 60 moves in the N direction by the fourth motor 75 being driven in reverse (S71). FIG. 23
As shown in (5), the third and fourth sensors 83, 84 are both turned on, and the base plate 60 and the roll film carrier 1 are turned on.
When it is detected that and have moved to the neutral position,
The fourth motor 75 is stopped and the base plate 60 stops its movement (S72, S73). Next, in step S74, the third motor 70 is driven to rotate in the reverse direction, and the slider 61
Is moved by a fixed distance from the initial position to the second sensor front stop position (FIG. 23 (5)). When the slider 61 moves to the second sensor front stop position, the holder portion 62 faces the M direction.

Discharge of Cartridge A As shown in FIG. 40, in the cartridge discharge routine,
The last-loaded cartridge An or the currently loaded cartridge A when the interrupt mode is set is discharged from the supply unit 6 and returned to the cartridge container 24. The operation in this routine is different from the operation in the replacement routine of the cartridge A shown in FIGS. 37 to 39, and the front face portion 38 of the carrier is not opened or closed. In step S75, FIG.
The same operation as steps S49 to S53 shown in FIG. That is, if the vertical scan is executed, the base plate 60 is moved along the vertical scan direction, and the base plate 60 and the roll film carrier 1 are moved to the neutral position. In steps S76 to S79, the same processing as steps S54 to 57 shown in FIG. 38 is performed, and the cartridge A loaded in the supply unit 6 is processed.
Is held (state of FIG. 24 (1)). Step S80-
In S89, steps S64 to S shown in FIGS.
The same processing as 73 is performed. That is, as shown in FIG. 24 (2), the slider 61 is moved to the initial position (S8).
0 to S82), and as shown in FIG. 25C, the base plate 60 is moved to the stop position at the end in the P direction, and the holder portion 6
The cartridge A held in No. 2 is returned to the tail end in the stacker 24 (S83-86). Then, FIG. 25 (4)
As shown in, after releasing the holding of the returned cartridge A, the base plate 60 is moved in the N direction, and the base plate 60 and the roll film carrier 1 are moved to the neutral position (S87 to S89).

In step S90, it is determined whether or not the interrupt mode is set, and if it is the interrupt mode, the process returns. If it is not in the interrupt mode, the last cartridge An is returned, so it is not necessary to prohibit removal of the stacker 24 and prohibition of increase / decrease of the cartridge A. Therefore, in step S91, the first motor 36 is reversely rotated and the moving claw portion 31 is moved to the initial position. As a result, the moving claw portion 31 retracts from the inside of the stacker 24, so that the engaging portions 31a and 31b of the moving claw portion 31 do not engage with the bottom wall of the stacker 24, and the stacker 2
4 can be removed. Further, step S92
Then, the solenoid 51 is turned off. As a result, FIG.
As shown in FIG. 5 (4), the inhibition lever 54 rotates about the support shaft 53 by the elastic force of the tension coil spring 55 and moves to a position retracted from the opening 24a of the stacker 24.

Loading of Interrupt Cartridge Ai As shown in FIG. 41, in this interrupt cartridge loading routine, the interrupt cartridge Ai by the ejecting mechanism 23 is used.
Are loaded. Before this processing is performed, the loaded cartridge Ax when the interrupt mode is set is set.
Regarding the above, the discharge from the supply unit 6 and the return to the cartridge container 24 are performed. Figure 26 (1)
As shown in, the base plate 60 and the roll film carrier 1 are moved to the neutral position, and the slider 61 is at the initial position. However, since it is the interrupt mode, step S
91 and S92 are not executed, and prohibition of removal of the stacker 24 and prohibition of increase / decrease of the cartridge A are continued.

In step S100, the third motor 7
0 is driven in the forward rotation, and the slider 61 moves from the initial position to J
Move in the direction. As shown in FIG. 26 (2), when the sixth sensor 86 is turned on and it is detected that the slider 61 has moved to the stop position at the end in the J direction, the third motor 70 is stopped and the slider 61 The movement is stopped (S101, S102). Next, the base plate 60 moves to the stop position at the end in the P direction (S103 to S105). At this time, the position of the holder portion 62 facing the L direction corresponds to the position of the third window portion 135 (see FIG. 1). In this state, the keep solenoid 106 is turned on, and the upper and lower arms 9
Reference numerals 1 and 92 hold the interrupt cartridge Ai set in the standby unit 132 (state of FIG. 27 (3)).

When the interrupt cartridge Ai is held,
The base plate 60 moves in the N direction (S107), and FIG.
As shown in (4), when the base plate 60 and the roll film carrier 1 move to the neutral position, the base plate 60 stops its movement (S108, S109). This movement of the base plate 60 causes the interrupt cartridge Ai to move to the standby unit 13.
It is taken in from 2. Next, the slider 61 moves in the K direction from the stop position at the end in the J direction to move the slider 61.
Moves to the stop position at the end in the K direction, the slider 61
Stops its movement (S111, S112). FIG. 28
As shown in (5), the holder 62 holding the interrupt cartridge Ai moves to L as the slider 61 moves.
From the direction to the M direction, and further, interrupt cartridge Ai
Are loaded into the supply unit 6. In this state, the keep solenoid 106 is turned off, and the holding of the interrupt cartridge Ai is released. Next, as shown in FIG. 28 (6), after the interrupt cartridge Ai is loaded into the supply unit 6 and released from holding, the slider 61 moves in the J direction from the stop position 1 at the end in the K direction. , Stop at the second sensor front stop position. The reason why the slider 61 is moved to the second sensor front stop position is to prevent the upper and lower arms 91, 92 and the like from interfering with the vertical scanning function of the roll film carrier 1, as described above.

Discharge of Interrupt Cartridge Ai As shown in FIG. 42, in this interrupt cartridge discharge routine, the interrupt cartridge Ai is discharged from the supply section 6 and returned to the standby section 132. The operation in this routine is almost the same as the ejection routine for the cartridge A shown in FIG. In steps S120 to S124, step S7 shown in FIG.
If the same processing as 5 to 79 is performed and the vertical scan is executed, the base plate 60 and the roll film carrier 1
After shifting and to the neutral position, the interrupt cartridge Ai loaded in the supply unit 6 is held (FIG. 2).
8 (1) same condition). In steps S125 to S127, the slider 61 is moved to the sixth sensor 8 instead of the initial position.
6 is moved to the stop position at the end in the J direction where it is turned on (the same state as in FIG. 27 (4)). Steps S128 to S130
Then, the same process as steps S83 to 85 shown in FIG. 40 is performed, and the base plate 60 is moved to the stop position at the end in the P direction. By this movement of the base plate 60, the interrupt cartridge Ai held in the holder portion 62 is returned to the standby portion 132 through the third window portion 135 (the same state as in FIG. 27C). In this state, the keep solenoid 106 is turned off,
The holding of the interrupt cartridge Ai is released. After the interruption cartridge Ai is returned to the standby unit 132 and the holding is released, steps S132 to S134 are performed as shown in FIG.
26, the base plate 60 is moved in the N direction, and the base plate 60 and the roll film carrier 1 are moved to the neutral position (the same state as in FIG. 26 (2)). ). Then, step S13
In 5 to S137, the slider 61 moves from the stop position at the end in the J direction toward the K direction and stops at the initial position.

Next, the operation control of the reader / printer equipped with the cartridge loader 21 when three operation modes of “auto mode”, “semi-auto mode” or “interrupt mode” are selected will be described. The roll film carrier 1 can automatically search for image information based on search information such as a blip mark attached to the microfilm F or an IMC (image management code). When performing automatic retrieval of image information, the operator operates the operation panel 1 of the retrieval device to retrieve the image retrieval information related to the image information to be retrieved or copied.
Input from 36 in advance.

The image search information includes (1) the roll number of the cartridge A containing the image information to be searched or copied,
(2) Frame number indicating which frame (number of chapters, how many pages) of the microfilm F contained in the cartridge A the target image information is input in (1) above, (3) The number of copies and the copy command when copying the target image information are included. The operator inputs these image search information by operating the keys on the operation panel 136. Further, the operator similarly inputs the image search information with respect to all target image information.

When the cartridge loader 21 is operated in the automatic mode, all image search information relating to the target image information contained in the cartridge A to be stored in the stacker 24 is input before operating the cartridge loader 21. I'll do it. In addition, the cartridge loader 21
When operating in the semi-auto mode and interrupt mode, the microfilm F accommodated in the cartridge A at the time of replacement of the cartridge A or interruption.
Enter the image search information for the target piece. A manual search is also possible.

Auto Mode Next, the operation control when the auto mode is selected as the operation mode of the cartridge loader 21 by the auto / semi-auto selection key 140 of the display panel 137 is shown in FIG.
9 and the flowchart shown in FIG. 30.

In this auto mode, the cartridge A containing the IMC-attached microfilm F is stored in the stacker 24, and retrieval, copying, etc. are automatically performed for all the cartridges A stored in the stacker 24. This is the operation mode that is mainly used when performing.

As shown in FIG. 29, step S200
Then, as to the image information to be searched or copied, the operator inputs the image search information such as the roll number, the frame number, the number of copies and the copy command from the operation panel 136 as described above. After inputting the image search information, each of the cartridges A containing the image information is stored in the stacker 24. The order of the cartridges A to be stored in the stacker 24 is
The input order of the image search information may be different. Then, the stacker 24 accommodating the cartridge A is set at a predetermined position on the mounting table 131 (S201).

When the auto mode is selected by the auto / semi-auto selection key 140 on the display panel 137 (S2
02), in step S203, the initialization routine shown in FIG. 33 is executed. Then, step S20
4, the cartridge increase / decrease prohibition process shown in FIG. 34 is executed, and the prohibition lever 54 moves the opening 2 of the stacker 24.
4a, the cartridge A stored in the stacker 24 is prevented from being removed or a new cartridge A being added while the cartridge loader 21 is operating. In step S205, the cartridge loading routine shown in FIG. 35 is executed, the first cartridge A is loaded in the supply section 6 of the roll film carrier 1, and the microfilm F accommodated in this cartridge A is loaded. Furthermore,
The movable claw portion 31 stands by at the stop position in the stacker, so that the stacker 24 is prevented from being removed. At this time,
In the roll film carrier 1, the IMC attached to the microfilm F is read (S206), and the microcomputer MC recognizes the roll number of the cartridge A in which the microfilm F is stored, the type of blip mark, and the like. When the loading of the microfilm F is completed, the searching routine shown in FIG. 36 is executed, and the next cartridge A is set on the set rod 33 while searching the microfilm F.

In step S207, the microcomputer MC determines whether or not there is the image search information of the cartridge A that matches the IMC, that is, the roll number recognized in step S206 is the roll number of the image search information previously input by the operator. To determine if it exists in. If the loaded cartridge A is specified by the operator, it is determined as YES, and the roll film carrier 1 conveys the microfilm F, and the blip mark attached to the microfilm F and the frame number of the image search information are set. Based on this, the target image information is automatically searched. When the image information that matches the frame number of the image search information is automatically searched in step S208, step S2
Go to 09. If it is determined in step S207 that the loaded cartridge A is not designated by the operator, and if it is determined in step S208 that there is no image information matching the frame number, step S220. (See FIG. 30) and a predetermined process is performed. This process will be described later.

When the image information matching the frame number of the image search information input by the operator is automatically searched, it is judged whether or not there is a copy command in the image search information. The retrieved image information is automatically copied according to the input page and the number of copies (S20).
9). When a plurality of target frames are present on the microfilm F, other image frames are automatically searched and copied sequentially (S208, S209). Note that the roll number of the image search information input first is already input as data so as to correspond to the IMC.

When all the retrieval and copying of the target image information of the microfilm F accommodated in the currently loaded cartridge A are completed, this microfilm F
Are automatically rewound and all are rewound on the rewinding reel 4 (S210). Then, in step S211, whether or not the search or the like has been completed for all the cartridges A stored in the stacker 24 is determined based on the calculated required number of times of replacement.

If the search or the like has not been completed for all the cartridges A, the process proceeds to step S213, and it is determined whether or not the interrupt key 141 is turned on and an interrupt request is made during the search in the auto mode. If there is no interrupt request, in step S214 in FIG.
39. The cartridge exchange routine shown in FIG. 39 is executed, and the ejection of the cartridge A loaded in the supply unit 6 of the roll film carrier 1 and the loading of the next new cartridge A are performed almost simultaneously in parallel. . Further, the microfilm F accommodated in the newly loaded cartridge A is loaded. Then, in the roll film carrier 1, the IMC attached to the newly loaded microfilm F is read (S215), and the microcomputer MC causes the roll number of the cartridge A in which the microfilm F is stored and the blip. The type of the mark 94 is recognized. Then, it returns to step S207. On the other hand, when it is determined in step S213 that the interrupt key 87 is turned on and an interrupt request is made, step S216
In, the process of the interrupt mode shown in FIG. 32 is executed. This process will be described later.

Steps S207 to S211, S21
3 to S215 and S207 are sequentially repeated for all the cartridges A stored in the stacker 24. When it is determined in step S211 that the search or the like has been completed for all the cartridges A based on the number of replacements calculated in advance, the process proceeds to step S212. In this step S212, the cartridge discharge routine shown in FIG. 40 is executed, and the roll film carrier 1
Is discharged from the supply unit 6 and returned to the stacker 24. Further, the moving claw portion 31 is moved to the initial position to release the prohibition of the removal of the stacker 24, and the prohibition lever 54 is moved to the position retracted from the opening 24a of the stacker 24 to release the prohibition of the increase / decrease of the cartridge A. It

As described above, the automatic search and copying in the auto mode are completed for all of the cartridges A in which the microfilm F with the IMC is stored and which are stored in the stacker 24.

Semi- Auto Mode Next, the operation control when the semi-auto mode is selected as the operation mode of the cartridge loader 21 by the auto / semi-auto selection key 140 will be described with reference to the flowchart shown in FIG.

In this semi-auto mode, the cartridge A containing the microfilm F without the IMC or the microfilm F without the blip mark 94 is stored in the stacker 24, and all the cartridges stored in the stacker 24 are stored. This is an operation mode mainly used when searching or copying the cartridge A.

As shown in FIG. 31, step S230.
Then, the operator puts in the stacker 24 the cartridge A group including the image information to be searched and copied, and
Set at a predetermined position of 31.

When the semi-auto mode is selected by the auto / semi-auto selection key 140 on the display panel 137 (S231), the initial setting routine (S232) is executed, and the cartridge increase / decrease prohibition process (S233) is executed. As a result, the prohibiting lever 54 projects to a position where it covers the opening 24a of the stacker 24, and the cartridge loader 2
It is prevented that the cartridge A stored in the stacker 24 is removed or a new cartridge A is added during the operation of 1. Next, the cartridge loading routine (S234) is executed, and the moving claw portion 31 waits at the stop position inside the stacker, so that the stacker 24 is prevented from being removed. At this time, the operator visually confirms the roll number of the loaded cartridge A.

In step S235, the operator manually searches for the desired image information for the cartridge A of that roll number. In the case of the cartridge A containing the microfilm F with the blip mark, the operator inputs the frame number and searches the microfilm F for desired image information by the search device. After copying the retrieved image information as desired, the operator rewinds the microfilm F. When the rewind of Microfilm F is completed,
In step S236, the operator uses the select key 142 to select whether to replace the cartridge A or reload the microfilm F in the cartridge A. In this way, the replacement and reloading of the cartridge A can be selected because the cartridge A is accidentally rewound when the operator accidentally rewinds the microfilm F during a manual search.
This is to prevent the automatic replacement of.

When the operator presses the left side of the select key 142 to select reloading of the film F, the microfilm F in the cartridge A being loaded is loaded.
Is loaded again (S237), and the process returns to step S235. Then, the operator manually searches for the target image information from the same microfilm F, searches for it with a search device, or copies the searched image information as desired. On the other hand, when the operator presses the right side of the select key 142 to select replacement of the cartridge A, the process proceeds to step S238. In step S238, it is determined whether the search or the like has been completed for all of the cartridges A stored in the stacker 24 based on the number of times of replacement calculated in advance.

If the search has not been completed for all the cartridges A, the process proceeds to step S240, and it is determined whether the interrupt key 141 is turned on during the search in the semi-auto mode and an interrupt request is made. If there is no interrupt request, a cartridge exchange routine is executed in step S241. Further, the microfilm F accommodated in the newly loaded cartridge A is loaded. After that, step S
Return to 235. On the other hand, if it is determined in step S240 that there is an interrupt request, the interrupt mode process shown in FIG. 32 is executed in step S242. This process will be described later.

Steps S235 to S238, S24
0, S241, and S235 are sequentially repeated for all the cartridges A stored in the stacker 24. Then, if it is determined in step S238 that the search and the like have been completed for all of the cartridges A based on the number of times of replacement calculated in advance, the process proceeds to step S239. In step S239, the cartridge ejection routine is executed. Further, the prohibition of the removal of the stacker 24 is lifted, and the prohibition of the increase / decrease of the cartridge A is lifted.

As described above, the search and copying in the semi-auto mode are completed for all of the cartridges A in which the IMC and the microfilm F without the blip mark are stored and which are stored in the stacker 24.

Interrupt Mode Next, the operation control when the interrupt key 141 of the display panel 137 is turned on and an interrupt request is made will be described based on the flowchart shown in FIG.

In the interrupt mode, the cartridge A other than the cartridge A stored in the stacker 24 is preferentially searched while the desired image information is searched or copied in the automatic mode or the semi-auto mode. This is an operation mode used when performing copying or the like.

When the interrupt key 141 is turned on during operation in the auto mode or the semi-auto mode, it is determined that there is an interrupt request in step S213 in the auto mode and in step S240 in the semi-auto mode, and the interrupt request is issued in steps S216 and S242, respectively. Mode processing is executed.

As shown in FIG. 32, when the interrupt mode process is started, first, in step S245, the process waits until the microfilm F in the cartridge A which has been searched at that time is rewound. When the rewind of the microfilm F is completed, step S24
6, the cartridge discharge routine is executed, and with respect to the loaded cartridge A, discharge from the supply unit 6 of the roll film carrier 1 and the stacker 24.
Will be returned to. However, since it is the interrupt mode, the prohibition of the removal of the stacker 24 and the prohibition of the increase / decrease of the cartridge A are continued.

Next, the operator inserts the interrupt cartridge Ai into the standby unit 13 without removing the stacker 24.
Set to 2 (S247). When the interrupt key 141 is turned on again in step S248, the interrupt cartridge loading routine shown in FIG. 41 is executed. The interrupt cartridge Ai is taken in through the third window 135 and is positionally loaded in the supply unit 6 of the roll film carrier 1.

In step S250, the operator manually searches for the target image information regarding the interrupt cartridge Ai. In the case of the cartridge A containing the microfilm F with the blip mark, the operator inputs the frame number and searches the microfilm F for desired image information by the search device. After copying the retrieved image information as desired, the operator rewinds the microfilm F. When the rewind of the microfilm F is completed, the operator selects the select key 142 in step S251.
The cartridge A is replaced or the microfilm F in the cartridge A is reloaded.

When the operator presses the left side of the select key 142 to select reloading of the microfilm F, the microfilm F is reloaded and the process returns to step S250. Then, the operator manually searches for the target image information from the same microfilm F, searches for it with a search device, or copies the searched image information as desired. On the other hand, when the operator presses the right side of the select key 142 to select replacement of the cartridge A, the process proceeds to step S252. In step S252, the interrupt cartridge discharge routine is executed, and the interrupt-searched cartridge Ai is discharged from the supply section 6 of the roll film carrier 1 and passes through the third window section 135 to wait section 1
Returned to 32.

If there is another cartridge Ai to be interrupt-searched, the cartridge Ai is set in the waiting section 132 (S247), and the interrupt key 141 is turned on again (S248). It is possible to copy, copy, etc.

When returning to the previous mode when the interruption search is completed and the interruption is completed, the operator selects the cartridge A.
After is discharged (S252), in step S254,
The auto mode or the semi-auto mode performed before the interruption is selected by the auto / semi-auto selection key 140, and the start switch (not shown) is turned on. With this operation, the cartridge loading routine is executed,
The first cartridge A among the remaining cartridges A not searched in the stacker 24 is loaded in the supply unit 6, and the microfilm F accommodated in this cartridge A is loaded. After this, it returns to the mode it was in before the interrupt.

When the interrupt search is performed in the automatic mode, the process returns to step S216, the IMC attached to the newly loaded microfilm F is read (S217), and then the process returns to step S207 to perform the above-described operation control. Done. When the automatic mode is switched to the interrupt mode, the image search information initially input in step S200 remains stored without being cleared, and it is not necessary to re-input the image search information. On the other hand, when the interrupt search is performed in the semi-auto mode, step S242
Returning to step S235, the operation control described above is performed.

As described above, the interrupt mode is selected during the operation of the auto mode or the semi-auto mode, and the preferential interrupt search and copying of the cartridges A other than the cartridges A accommodated in the stacker 24 are completed.

Switching between auto mode and semi-auto mode
The next place, when there is no cartridge A and image information corresponding to the image retrieval information input by the operator, that is,
The operation control when NO is determined in S207 and S208 will be described.

When an operator makes a mistake, that is, when there is an input error when inputting image search information,
The input is correct but the wrong cartridge A is stacked 24
If it is stored in the cartridge, it is determined that there is no cartridge A that matches the image search information (S20
7) It is determined that there is no image information that matches the image search information (S208). In this case, as shown in FIG. 30, in step S100, the microfilm F accommodated in the loaded cartridge A is rewound and the cartridge loader 21 suspends its operation.

In such a case, the operator switches the operation mode of the cartridge loader 21 from the automatic mode to the above-mentioned semi-auto mode, and the microfilm F contained in the cartridge A being loaded.
With regard to, a manual search can be performed. That is, in step S221, the operator selects the semi-auto mode with the auto / semi-auto selection key 140 and turns on the start switch. Next, in step S222, the operator uses the select key 142 to select whether to replace the cartridge A or reload the microfilm F in the cartridge A.

When the cartridge A is the object of retrieval but there is an error in inputting the frame number, the operator presses the left side of the select key 88 to select reloading of the microfilm F. When the wrong cartridge A is stored in the stacker 24, the operator pushes the right side of the select key 88 to select the replacement of the cartridge A.

When the reloading of the microfilm F is selected, the reloading of the microfilm F is performed. Next, the operator manually retrieves desired image information from the same microfilm F (S223). For microfilm F with a blip mark, the operator enters the correct frame number,
The desired image information may be retrieved from the microfilm F by a retrieval device. If the desired image information is obtained as a result of a manual search or the like, the operator copies the image information as desired and then rewinds the microfilm F. When the rewind of the microfilm F is completed, the operator, in step S224,
By using the select key 142, the cartridge A is replaced, or the microfilm F in the cartridge A is replaced.
Select whether to reload and search.

When the operator presses the right side of the select key 142 to select the replacement of the cartridge A in step S224, the cartridge replacement routine is executed in step S225 and the cartridge 6 is loaded in the supply section 6 of the roll film carrier 1. The ejection of the existing cartridge A and the loading of the next new cartridge A are performed in parallel at substantially the same time. Further, the microfilm F accommodated in the newly loaded cartridge A is loaded.

To continue the semi-auto mode, steps S223 to 226 described above are repeated. On the other hand, when ending the semi-auto mode and returning to the auto mode, the operator selects the auto mode with the auto / semi-auto selection key 140 in step S227 after the cartridge A is replaced (S225), and turns on the start switch. To do. Then, after the IMC attached to the newly loaded microfilm F is read (S228), the process returns to step S207 and the above-described operation control is performed. Even if you switch from auto mode to semi-auto mode and return to auto mode again,
The image search information initially input in step S200 remains stored without being cleared, and it is not necessary to re-input the image search information.

Further, since the wrong cartridge A has been stored, the cartridge A is stored in step S222.
Even when the replacement is selected, the same operation as described above is performed, and after the cartridge is replaced (S225), the automatic mode is selected (S227) to return to the automatic mode.

If the cartridge A does not match the image search information input by the operator, or if there is no image information matching the image search information, the incorrect image search information is not searched and remains until the end. However, it may be cleared after the search for all the cartridges A is completed.

As described above, the reader / reader of this embodiment
In the printer, when the vertical scan function is used during the search for microfilm, the roll film carrier 1 is moved to the base plate 60 side without changing its position,
The relative position between the roll film carrier 1 and the cartridge loader 21 is corrected, the both 1, 21 are returned to the neutral position, and the cartridge A is replaced. With such a configuration, the relative position deviation can be easily and quickly corrected, and the replacement time of the cartridge A can be shortened to achieve high-speed retrieval of image information in the reader / printer. Further, since it is not necessary to store the movement amount of the roll film carrier 1, it is not always necessary to electrically perform the vertical scan of the roll film carrier 1, and it is not necessary to prohibit the vertical scan manually. Therefore, the vertical scan manually is performed. Even if the cartridge loader 21 is incorporated in the reader / printer that performs scanning, the replacement operation of the cartridge A can be performed without any trouble.

Also, the roll film carrier 1 and the cartridge loader 2 when the vertical scan is performed.
Although the case where the deviation of the relative position with respect to 1 is corrected is shown, even if the vertical scan is not performed, the roll film carrier 1 and the cartridge loader 21 are affected by the stop accuracy and vibration of the motor. The relative position with may shift. Even in such a case, in this embodiment, the roll film carrier 1 and the cartridge loader 2 are
It is possible to correct the deviation of the relative position with respect to 1. In this way, the relative positions of the roll film carrier 1 and the cartridge loader 21 are constantly corrected, and the cartridge loader 21 can reliably perform a predetermined operation.

Further, in the reader / printer of this embodiment,
The prohibition lever 54 that moves to a position covering the opening 24a of the stacker 24 prohibits the removal of the cartridge A and the addition of a new cartridge A during the operation of the cartridge loader 21. Therefore, malfunction of the cartridge loader 21 due to increase / decrease of the number of the cartridges A, failure due to erroneous operation by the operator, and conveyance error of the cartridge A can be surely prevented, the reliability of the cartridge loader 21 is improved, and eventually the reader / printer. It is possible to improve the reliability of the search and copying of the microfilm F in FIG. In particular, as in this embodiment, the cartridge loader 21
In the reader / printer in which the required number of replacements of the cartridge A is calculated in advance at the time of starting the operation, it is extremely useful to prevent the malfunction of the cartridge A in order to prevent the cartridge A from increasing or decreasing.

Further, in the reader / printer of this embodiment,
Engagement portions 31a and 31b that are engageable with the bottom plate of the stacker 24
By moving the moving claw portion 31 provided with a predetermined position in the stacker 24, the removal of the stacker 24 itself during the operation of the cartridge loader 21 is prohibited. Therefore, the malfunction of the cartridge loader 21 due to the removal of the stacker 24 can be reliably prevented, and the reader / reader
It is possible to improve the reliability of searching and copying the microfilm F in the printer.

Further, since the reader / printer of this embodiment has three operation modes, which are the auto mode, the semi-auto mode, and the interrupt mode, it is possible to execute the operation corresponding to various retrieval methods and applications. In addition, since the operation corresponding to the type of microfilm used can be executed, the search ability when searching using the cartridge loader is improved, and further, the optimum usage mode suitable for each user can be obtained. The cartridge loader can be operated, and the convenience of the cartridge loader is improved.

Further, the reader / printer of this embodiment is for interrupting the cartridges other than the cartridge A stored in the stacker 24 without removing the stacker 24 when the interrupt mode is instructed during the operation in the auto mode or the semi-auto mode. Since the cartridge Ai can be loaded and ejected preferentially, the search capability and convenience when searching using the cartridge loader 21 are further improved.

In the above-described embodiment, the loading mechanism 22 and the stacker 24 of the cartridge loader are configured so that their relative positions with respect to the roll film carrier 1 do not slip even if the vertical scan is performed. , But is not limited to this case. For example, when the stacker 24 does not move together with the roll film carrier 1, the shape and length of the set bar 33 of the loading mechanism 22 are set to a shape and length that allow the positional displacement between the loading mechanism 22 and the stacker 24. If the set rod 33 is configured to be driven by a motor, and a switch or a sensor for detecting that the cartridge A is slid by the set rod 33 to a predetermined position on the carrier front surface portion 38 rotated in the I direction is provided. good.

As described above, according to the image projection apparatus of the present invention described in claim 1, the film carrier moves from the home position when an instruction to take out the microfilm from the film carrier is given. In the meantime, the position of the film carrier remains the same, and the take-out means side is moved by the take-out means moving means.
The take-out means is moved to a position corresponding to the position of the film carrier. As a result, the relative positional deviation between the film carrier and the take-out means is corrected without returning the film carrier side to the home position, and the take-out means moves to a position where the microfilm is taken out from the film carrier. According to such a configuration,
Misregistration of relative positions can be performed easily and quickly, and the speed of retrieval of image information in the image projection apparatus can be increased by shortening the microfilm take-out time. Further, since it is not necessary to store the moving amount of the film carrier, the moving means for the film carrier is not limited to the electric driving means, and may be a manual moving means. For this reason, it is possible to take out the microfilm without any trouble even with an image projection apparatus having a manually moving means for the film carrier.

According to the image projecting device of the present invention, the cover member moves to a position where it covers the opening of the cartridge housing portion during operation of the cartridge loader.
